Justification
Although this species may have a small range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Distribution and populationMargarops fuscus is endemic to the Lesser Antilles, with populations on
St Martin,
St Barthelemy,
St Kitts and Nevis,
Antigua and Barbuda,
Montserrat (to U.K.),
Guadeloupe (to France),
Dominica,
Martinique (to France),
Grenada,
St Lucia and the island of St Vincent,
St Vincent and the Grenadines (del Hoyo
et al. 2005). The subspecies
atlantica, endemic to
Barbados, has not been located in recent searches and is likely to be extinct (Brewer 2001).
Population justificationThe global population size has not been quantified, but this species is described as 'common' (Stotz et al. (1996).
Trend justificationThe population trend is difficult to determine because of uncertainty over the impacts of habitat modification on population sizes.
